Pengaruh pembuatan batu bata terhadap produktivitas tanah di desa Candi Kecamatan Ampel Kabupaten Boyolali (The Effect of Brick Production to The Productivity of Land at Candi Village, Ampel, in Boyolali Regency)

The aim of this research is to analyze the effect of brick production on the productivity of land at Candi village, Ampel, Boyolali Regency of Central Java. This study used economic approaches Le: benefit foregone approach and economic rent approach. The benefit foregone approach only accounts for value of land production foregone, whereas economic rent approach included the land fertility in addition to benefit foregone. The result of the emperical study indicated that by using economic rent approach, brick production decreased the land productivity and it was not feasible that was with a discount rate of 15 percent, the B/C ratio was less than 1 and NPV aquals to - 321.938. Whereas by using benefit foregone approach brick production, it was found that although ii reduced the kind productivity, it was feasible that it was with a discount role of 15 percent, the B/C ratio was bigger than 1 and NPV equals to 283.651. All respondents said that brick production had reduced the land fertility, but the brick production had reduced the land fertility, but the production of brick was almost without financial investment. More than 40 percent of respondent were under 40 years old and 90percent of them dit not complete primary school. The average land holding of respondents was 1.873 m2, even 50 percent of the respondents were holding no more than 1.500 m2. Key words: economic rent -- land productivity benefit foregon

KONTRIBUSI SEKTOR KEHUTANAN PADA PEMBANGUNAN DAERAH KABUPATEN BLORA

 This study is aimed to establish a more reliable measurement called Environmentally Friendly GRDP case of the forestry sector of Blora. The study is adopting the descriptive analytical approach by computing the depletion value of forest natural resources and the degradation value of the environment related to the forest cutting using primary and secondary data. Results of the study indicate that depreciation of forest resources were quite high (approximately 30% of the forest GRDP). So if depreciation of natural resources and environment is neglected and not accounted in the report of GRDP, in turns the sustainability of forest and the economy is in danger. It is therefore to be recommended that Green GRDP must be adopted and computed in order the Governement of each region of Indonesia are able to prepare a better plan and management of the natural resources for long term sustainbale development. Keywords: environmentally friendly GRDP, depletion, degradation, unit rent, benefit transfe

Contributions of Enim Watershed in Production of Irrigation Rice Using Benefit and Cost Analysis

Abstract— Population growth impacts on accumulating basic need. Basic foodstuff of Indonesia people is rice. The rice is derived from paddy field. The availability of paddy land use need to be maintained due to the continuously of supporting aspects ie water, paddy field. Therefore,  it is necessary to manage rice crops to yield more production. Irrigation is one way to increase rice production. Irrigation plays an important role in the success of rice production. An important role of this irrigation should be assessed economically. The economic value of irrigation for paddy production needs to be studied. An important role of the irrigation should be assessed econmically. The economic value of irrigation for paddy production needs to be studied. Study of economic value is important so that people know that the irrigation water is an important contribution in the production of rice in addition to seeds, fertilizer and labor. It is necessary for economic calculation.This study aimed to quantify the economic value of watersheds to irrigate rice fields. Economic value calculation is conducted using benefit and cost benefit analysis on use of irrigation watershed in Cahaya Alam village. Muara Enim regency in South Sumatera of provinceKeywords— Enim watershed, irrigation, benefits and costs analysi

Dampak Pertambangan Batubara Terhadap Kesehatan Masyarakat Sekitar Pertambangan Batubara (Kajian Jasa Lingkungan Sebagai Penyerap Karbon)

Ekosistem memiliki nilai manfaat melalui fungsi-fungsi yang dimilikinya. Jasa lingkungan merupakan sebuah produk dari ekosistem. Kegiatan alih fungsi kawasan hutan seperti pertambangan batubara yang menyebabkan hutan tidak bervegetasi dan terlepasnya karbon ke udara dapat menyebabkan hilangnya fungsi tersebut. Dampak terhadap hilangnya nilai jasa lingkungan dan manfaat lingkungan bagi masyarakat. Dampak lanjutan yang timbul adalah terhadap gangguan kesehatan dan biaya eksternal masyarakat khususnya yang bermukim sekitar pertambangan batubara. Dampak yang timbul merupakan ekternalitas negatif kegiatan pertambangan terhadap masyarakat. Penelitian yang dilakukan di PTBA Tanjung Enim tahun 2011 secara survey bertujuan untuk mengidentifikasi jenis gangguan dan upaya yang dilakukan untuk mengatasi gangguan kesehatan yang dialami masyarakat serta biaya yang dikeluarkan untuk mengatasi gangguan tersebut. Hasil penelitian ditemukan adanya berbagai jenis gangguan kesehatan masyarakat , dan ISPA merupakan jenis gangguan kesehatan yang paling banyak dialami masyarakat. Biaya eksternal kesehatan masyarakat rata-rata per responden yang bermukim sekitar pertambangan batubara TAL PTBA sebesar Rp 20.794.- Hasil penelitian gangguan dan biaya kesehatan masyarakat yang timbul sebagai eksternalitas negatif kegiatan pertambangan batubara terhadap masyarakat yang bermukim sekitar TAL PTBA menjadi keterbaruan novelty dari study ini, dapat digunakan oleh pemerintah, stakeholders, dan investor tambang untuk menentukan jenis gangguan kesehatan masyarakat dan biaya kesehatan masyarakat yang timbul sebagai eksternalitas negatif kegiatan pertambangan batubara secara terbuka
